Harvesting equipment - Requirements for cutting elements - Part 1 : blades used on rotary disc mowers and rotary drum mowers

This document specifies requirements for blades used as cutting elements on rotary disc mowers and rotary drum mowers used for forage crop harvesting in agriculture only (as defined in ISO 4254-12) that are mounted, semi-mounted, trailed or self-propelled. It specifies requirements for testing and marking of such blades. This document is not applicable to blades used on: — flail mowers; — large rotary mowers covered by ISO 4254-13; — arm-type large rotary mowers; — pedestrian-controlled motor mowers; — lawn mowers covered by the ISO 5395 series. NOTE 1 The main purpose of this document is to set material characteristics. Blades on rotary drum and rotary disc mowers are exposed to considerable centripetal forces and impacts with foreign objects. A bend test and impact test to check the brittleness and toughness of the material are therefore included in this document. NOTE 2 This document does not specify dimensional requirements.

Harvesting equipment - Requirements for cutting elements Part 2 : blades used on large rotary mowers

This document specifies requirements for blades used as cutting elements on large rotary mowers (as defined in ISO 4254-13) for shredding crop residue, grass and small brush by impact. It specifies requirements for testing and marking of such blades. This document is not applicable to blades used on: — rotary disc mowers, rotary drum mowers, and flail mowers designed for forage crop harvesting as covered by ISO 4254‑12; — arm-type large rotary mowers; — pedestrian-controlled motor mowers; — lawn mowers covered by the ISO 5395 series. NOTE 1 The main purpose of this document is to set material characteristics. Blades on large rotary mowers are exposed to considerable centripetal forces and impacts with foreign objects. A bend test and Charpy impact test to check the brittleness and toughness of the material are therefore included in this document. NOTE 2 This document does not specify dimensional requirements.

ZOOM ON ... the Requirements department

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
